    How do you plan to handle bad actors creating biblical amounts of servers dynamically and then spamming at line rate from all of those servers?

      Why would they need to "create servers" instead of just throwing UDP packets at you like a normal DDOS?
      1. Retr0id · · focus · HN ↗
        Because throwing UDP packets requires a bandwidth advantage (aside from reflection attacks), whereas application-layer attacks can impose an outsized cost on the victim.

          But you said line rate - that's a simple bandwidth exhaustion.
          1. Retr0id · · focus · HN ↗
            Line rate of sender != line rate of receiver (I am also not GP).

              It probably is though. They're probably both 1Gbps Ethernet.

                It's a federated network, so even if everyone has symmetrical 1Gbps links you cant throw 1Gbps at all of them at once.
